Coreopsis plant named ‘Cherry Lemonade’

ABSTRACT

A new and distinct  Coreopsis  plant named ‘Cherry Lemonade’ characterized by yellow foliage, red flowers, and a dwarf habit.

Botanical designation: Coreopsis hybrid (parents unknown).

Variety denomination: ‘Cherry Lemonade’.

Cross reference to: co-pending applications for Coreopsis ‘Pink Lemonade’ (U.S. application No. 11/343,831 and ‘Strawberry Lemonade’ (U.S. application No. 11/344,356).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct plant of Coreopsis and given the cultivar name ‘Cherry Lemonade’. Coreopsis is in the family Asteraceae. This new cultivar originated from offspring located at the nursery in Canby, Oreg. and reproduced in tissue culture where further selections were made. This selection was made for its cherry red flowers.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cherry Lemonade’. These characteristics in combination distinguish ‘Cherry Lemonade’ as a new and distinct cultivar:

-   -   1. Golden yellow foliage.     -   2. Unique red daisy type flowers.     -   3. Dwarf mounding habit.     -   4. Very free flowering.

This new cultivar has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by cuttings and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg. shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The photograph shows a one year old Coreopsis ‘Cherry Lemonade’ growing in the ground in the field in August in Canby, Oreg.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Coreopsis cultivar based on observations of a one-year-old specimen grown in a container in the greenhouse over the winter and then planted on May 1^(st) in the ground in the trail fields in full sun. The data was taken in August from this material. The trial fields are under typical outdoor conditions in Canby, Oreg. Canby in Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95 degrees F. in August to 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart.

COMPARISONS TO SIMILAR COREOPSIS

Compared to Coreopsis ‘Limerock Ruby’ (U.S. Plant Pat. No. 15,455), this new cultivar has the same flower size but has red flowers rather than rose, a much shorter habit, and yellow foliage rather than green.
